1. Structure of Met Coke -- Coke Strength after Reactivity 65 Description

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1) How to guarantee the quality of the products

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

2) What are coke's main physical properties?

on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.

The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)

Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);

Ignition temperature (air) is 450-650 ℃.

3) How about your company

Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on.

Q:The coke is divided into several separate uses
Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
Q:Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the comprehensive utilization of raw materials in the following process
(1) according to the definition of replacement reaction, there are two kinds of compounds in the reaction of II, contains two kinds of compounds in the product, so it is not the replacement reaction of reactants, IV no elemental, so it is not a replacement reaction, V reaction is a chemical reaction, I and III reaction with replacement reaction conditions, so is the replacement reaction,
Q:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough
Q:What is the use of petroleum coke
Petroleum coke, petroleum coke. Solid residues produced by high temperature coking of residual oil, residual oil or bitumen from petroleum refining.
Q:How long should it be to store coke in the open air
And the most important thing is to avoid the sun. Coal and coke, like the sun, the temperature inside the stack is very high. So try to cool down.
Q:Who knows the proportion of pig iron and coke used in Cupola
There is doubt: the export rate is lower than the standard exception.4, blank blank processing: according to customer requirements of different direct sales, some need to continue processing after the sale, the ordinary rough machined after a blank rate of about more than 70%, about 30% (excluding scrap scrap), dryer enterprises after after machining yield is about 25% ~ 30% (including waste scrap and iron, basically use recycled material, material waste accounted for ratio of 30% ~ 40%). To 1.5M x 2M cylinder, for example, rough weight of about 5.8 tons ~ ~ 6 tons (standard cylinder, including the cylinder head) cylinder head rough weight of about 1.7 tons ~ ~ 1.8 tons, cylinder weight of about about 4.2 tons. After processing, the cylinder head weighs about 0.5 tons to 0.6 tons, accounting for the proportion of about 65% to 70% head (excluding scrap, scrap accounted for about 10%, blank cylinder head and iron) accounted for about 30% ~ 35% blank cylinder head, accounted for the proportion is about 40% recycled waste, scrap iron accounted for under foot material proportion 60%, enterprises can not return direct sales (currently, only production enterprises can use recycled scrap iron). Total iron blank ratio is about 15% ~ 18%.
Q:Coke is how to make it? What is the use?
Improving the coal preparation process is the way to expand the coking coal source and improve the quality of coke. At present, most of the coking plants in China adopt the mixed grinding process. This process can not be treated according to the different hardness of coal, so it is only suitable for the coking coal with good caking property and uniform coal quality. A new coal preparation process has three kinds: single comminution process is various, coal crushing alone first, and then according to the provisions of the proportion, then mixing; the first group grinding process, hardness of similar kinds of coal, according to the proportion of each group, were sent to the respective crushing requirements the particle size, then mixing the crushing process; is crushed to a certain degree of coal sieving, the coarse grain group screened were crushed again, so that the coarse grain group cohesiveness, inert material with high content of ground fine, avoid good bonding facies excessive grinding components.
Q:Why use coke instead of carbon in blast furnace ironmaking
The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.
Q:How to determine the maturity of coke or not?
The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.
Q:Dry or dry carbon carbon, coke or coke, and I do not know which word of
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke.
